You may have a misunderstanding here. Neovim, while it is a ground up rewrite of vim, didn't break people's configs. The team made it a point to maintain backwards compatibility while positioning themselves to be able to move towards using lua as their config language.

Yes, but then Vimscript wasn't a very good language; whereas Lua, Python (and many others Neovim enabled support for) are great languages.

The benefit of a much better language is enticing; making a language much better than Emacs Lisp, however, is not so easy.

Except the specific rewrite the op was talking about was moving from elisp to scheme. It's one thing to support a limited language like vimscript, it's a whole other thing to reproduce the semantics of elisp in scheme.
